As to your question about prayer and whether it is necessary
to recite the prayers of only the Central Figures of our Faith, we have been
asked to quote here the following two excerpts on this subject, from letters
written by Shoghi Effendi's secretary on his behalf:"...as the Cause embraces members of all races and religions we should be careful not to introduce into it the customs of our previous beliefs. Bahá'u'lláh has given us the obligatory prayers, also prayers before sleeping, for travellers, etc. We should not introduce a new set of prayers He has not specified, when He has given us already so many, for so many occasions.”
“He thinks it would be wiser for the Bahá'ís to use the
meditations given by Bahá'u'lláh, and not any set form of meditation
recommended by someone else; but the believers must be left free in these
details and allowed to have personal latitude in finding their own level of
communion with God.”
As to the reading of prayers or selections from the Sacred
Writings of other religions such readings are permissible, and indeed from time
to time are included in the devotional programmes of Bahá'í Houses of Worship,
demonstrating thereby the universality of our Faith.
